Effect of PPARgamma inhibition on pulmonary endothelial cell gene expression: gene profiling in pulmonary hypertension.

Peroxisome proliferator-activated receptor type gamma (PPARgamma) is a subgroup of the PPAR transcription factor family. Recent studies indicate that loss of PPARgamma is associated with the development of pulmonary hypertension (PH). We hypothesized that the endothelial dysfunction associated with PPARgamma inhibition may play an important role in the disease process by altering cellular gene expression and signaling cascades.

Recombination events between the p47-phox gene and its highly homologous pseudogenes are the main cause of autosomal recessive chronic granulomatous disease.

Chronic granulomatous disease (CGD) is an inherited disease caused by defects in the superoxide-generating nicotinamide adenine dinucleotide phosphate (NADPH) oxidase of phagocytes. Genetic lesions in any of 4 components of this antimicrobial enzyme have been detected. Family-specific mutations are found in 3 of 4 forms of CGD due to deficiencies of the gp91-phox, p22-phox, and p67-phox genes.

In vitro antitumor activity of 2'-deoxy-5-fluorouridine-monoclonal antibody conjugates.

5-Fluorouracil (5-FU) is an anticancer drug used in patients for the treatment of gastric and breast cancer and used either alone or in combination with methotrexate is one of the few drugs with some effect on colon cancer. 2'-Deoxy-5-fluorouridine (5-FUdr) (1) is an analogue based on 5-FU and can be covalently linked to a murine anti-Ly-2.1 monoclonal antibody (mAb) with the active ester derivative of 2'-deoxy-5-fluoro-3'-O-(carboxypropanoyl)uridine (5-FUdr-succ) (4).
